Description

Technical Field

[0001] The utility model belongs to the field of security fences, in particular to a security device. Background Art

[0002] Security can be understood as an abbreviation for "safety precautions." According to current Chinese dictionaries, safety means being free from danger, harm, and accidents. Precautions mean being prepared and alert. Precautions refer to being ready to deal with an attack or avoid harm, while alertness refers to both defense and protection. Installing fences around locations requiring safety precautions is also a form of security. Patent publication number CN220889754U, entitled "A Variable Security Fence," discloses a security fence with a complex structure. While the fence's height is adjusted to prevent pedestrians from climbing over it, pedestrians can still climb the fence, and if the height adjustment isn't timely, there's a possibility of climbing over it. Therefore, we've designed a security device that can't be climbed. Utility Model Content

DETAILED DESCRIPTION

[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] A security device, such as Figure 1 、 2 As shown in Figures 3 and 4, it includes a vertical bar 1, two vertical bars 1, and a horizontal plate 2 fixedly installed at the bottom of each vertical bar 1. A vertical plate 3 is provided between the two vertical bars 1. Both sides of the vertical plate 3 are fixedly connected to one side of the vertical bar 1 in sequence. A plurality of through slots 4 are provided on the upper and lower sides of the vertical plates 3. In this embodiment, there are four through slots 4 in total, and they are symmetrically distributed left and right and up and down. Sprockets 5 are rotatably installed in the through slots 4. The corresponding sprockets 5 are connected by chains 6. The chains 6 are located on the outer periphery of the vertical bars 3 and will not be affected by the vertical bars 3 when rotating. A plurality of horizontal bars 7 are fixedly installed on the outer periphery of the chains 6. The plurality of horizontal bars 7 are evenly distributed along the outer periphery of the chains 6. The utility model has a simple structure and an ingenious design. When a pedestrian steps on the horizontal bar 7, the horizontal bar 7 drives the chain 6 downward under the action of the pedestrian's own gravity, thereby preventing the pedestrian from climbing the fence and ensuring that the pedestrian cannot climb over the fence. It can meet actual needs and is suitable for promotion. When using the present invention, first place the entire device in a suitable position. The two vertical bars 1 and the horizontal board 2 form a fence. The position where safety precautions are required is surrounded by several fences. When a pedestrian wants to climb the fence, the pedestrian steps on the bottom horizontal bar 7. At this time, the horizontal bar 7 drives the chain 6 to move downward under the pedestrian's own gravity. When the pedestrian continues to step on the upper horizontal bar 7, the corresponding horizontal bar 7 continues to move downward, thereby ensuring that the pedestrian cannot climb above the vertical board 3 and cannot climb over the fence.

[0017] Specifically, as shown in the figure, in this embodiment, slide grooves 20 are respectively provided on both sides of the through groove 4 on the upper side, and sliders 21 are slidably installed in the slide grooves 20. The sliders 21 can only slide up and down in the slide grooves 20. The sprocket 5 is fixedly installed on the rotating shaft 22. The two ends of the rotating shaft 22 are rotatably installed on the sliders 21 on both sides in turn. The two ends of the rotating shaft 22 are rotatably installed on the sliders 21 on both sides through bearings in turn. The sliders 21 and the corresponding slide grooves 20 are elastically connected by springs 27. A pressure sensor 23 is fixedly installed in the slide groove 20, and a battery 24, a controller 25, and a buzzer alarm 26 are fixedly installed on the vertical rod 1. In this embodiment, the buzzer alarm 26 is provided on both sides and is fixedly installed on the vertical rods 1 on both sides in turn. The battery 24 supplies power to the pressure sensor 23, the controller 25, and the buzzer alarm 26. The controller 25 is electrically connected to the pressure sensor 23 and the buzzer alarm 26. When two people cooperate, one person holds a cross bar 7, and the chain 6 can no longer drive the cross bar 7 to rotate. The other person climbs up along the cross bar 7. At this time, the stepped cross bar 7 drives the chain 6 to move downward, and the chain 6 drives the upper sprocket 5 and slider 21 to move downward. The distance that the sprocket 5 moves downward is very small and will not cause the chain 6 to fall off. The spring 27 is compressed. When the slider 21 contacts the pressure sensor 23, the pressure sensor 23 detects the pressure from the slider 21 and feeds back the information to the controller 25. The controller 25 controls the buzzer alarm 26 to sound an alarm, attracting the attention of the staff.

[0018] Specifically, as shown in the figure, the top of the vertical pole 1 in this embodiment is fixedly mounted with an alarm light 30, which is electrically connected to the controller 25 and powered by the battery 24. When someone climbs, the controller 25 controls the buzzer alarm 26 to sound an alarm and can also control the alarm light 30 to start flashing, which can attract the attention of nearby staff.

[0019] Furthermore, as shown in the figure, two grooves 40 are formed on the vertical plate 3 of this embodiment. The two grooves 40 are symmetrically distributed. A limit rod 41 is hinged in the groove 40 via a torsion spring. The limit rod 41 is fixedly mounted on the rotating shaft. The two ends of the rotating shaft are respectively rotatably mounted in the groove 40 via bearings. The torsion spring is mounted on the rotating shaft. The two ends of the torsion spring are fixedly connected to the rotating shaft and the inner wall of the groove 40 in sequence. The torsion spring is not shown in the figure. The limit rod 41 is formed with an arc groove 42, and the cross bar 7 is engaged with the arc groove 42. During installation, one end of the limit rod 41 is located on the inside. When a dangerous situation occurs, the limit rod 41 is rotated out of the groove 40 and the cross bar 7 is engaged in the arc groove 42. At this time, the cross bar 7 cannot move further, and climbing can be performed from the inside, facilitating escape.

[0020] Furthermore, as shown in the figure, a stopper 50 is fixedly installed in each of the chute 20 of this embodiment, and the upper end of the stopper 50 is flush with the upper end of the pressure sensor 23. When the slider 21 contacts the pressure sensor 23, the slider 21 contacts the stopper 50, which can prevent the slider 21 from moving further downward and damaging the pressure sensor 23.

[0021] Furthermore, as shown in the figure, the cross plate 2 of the present embodiment is provided with a plurality of bolt holes 60. During installation, bolts can be put into the bolt holes 60, and the cross plate 2 can be fixedly installed in a designated position by the bolts, making the device more stable.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
